Adjusting the injection pump Bosch

In the fuel system of a diesel car, the quality of a high-pressure fuel pump (HP injection pump) plays an important role . Bosch is a company with worldwide fame. Under this brand are produced high-quality spare parts for various models of cars. Of course, the value of the goods of this firm is higher than that of Chinese competitors. But you can not save on fuel pump.

The task of the unit is to create the pressure necessary for the productive operation of the motor. If you hear noises when starting the engine, and fuel consumption increases significantly, contact the service center and go through the diagnostics.

If the water could get into the system, as well as using low-quality fuel, the adjustment of the Bosch injection pump is necessary. A similar procedure will be required if the pump pressure is insufficient, and also if the injectors are worn out or strongly clogged and work inappropriately. If the plunger pair is faulty, it must be replaced. It is worth paying attention to the fact that often because of the breakdown of one detail, the nearby ones also suffer. Therefore, in the presence of even minor faults, it is better to conduct an appropriate diagnosis in a good car service.

Adjustment of the injection pump Bosch should be carried out and if you find that fuel leaks. If this problem is left unattended for a long time, you may need a long and expensive repair. If the tightness is broken, this leads to a decrease in pressure. And this problem affects the performance of the pump and can even lead to a fire in the motor.

If you need to repair the fuel pump Bosch, after it must be done the adjustment. It is performed using a special stand that accurately measures the angles of the preliminary stroke of the plunger pair, determines the start of the fuel supply and other important characteristics.

Such work can only be carried out using specially designed equipment. And, of course, do not trust such work for amateurs.

The Bosch injection pump is a device that requires professional handling. It is better to check it at the stand. If you still decide to adjust the device with your own hands, first rinse it with a special remedy. This is necessary in order to remove the mud deposits and make the inner surface smooth.

Then you need to check the labels ahead of the injection. To do this, unscrew the valve and check it. The part must be in the closed position. Using a hammer, tap lightly on the top of the valve. To close the bypass, cage the inside.

The next step is the adjustment of the cyclic delivery of the Bosch injection pump. It is necessary to unscrew or vice versa - to screw in and tighten the lock nut (if necessary). Then make an idling adjustment. This is done in the same way as in the case of cyclic feeding. The interval from 770 to 780 rpm is considered the norm. The final stage is the adjustment of the hydraulic corrector. The thrust is reduced by turning the pin in the counterclockwise direction.

As you can see, you can do this job yourself. But the ideal option is to entrust it to specialists.
